n8n GDPR DPIA Screening Workflow w/ Groq, Forms & Discord

Automate GDPR DPIA screening in n8n—then get REQUIRED alerts to Discord

This n8n workflow turns your GDPR DPIA screening into a repeatable, evidence-backed process: it collects DPIA inputs via an n8n Form, scores them against editable EDPB/WP29 DPIA screening criteria in n8n Data Tables, uses Groq to validate additional criteria with verbatim quotes, records results in tables, and posts required outcomes to Discord (including a weekly digest).

What this workflow does

• One-time setup (manual): creates three n8n Data Tables—dpia_criteria, dpia_screenings, and dpia_findings—and populates dpia_criteria with nine EDPB/WP29 DPIA screening criteria.
• Collects screening data: receives a submission from an n8n Form including the project description, data categories, data subjects, scale, and yes/no/not sure answers.
• Deterministic scoring: loads criteria from dpia_criteria, counts criteria met based on form answers, scale thresholds, and keyword matches in the submitted description.
• Groq quote validation: sends the full criteria list and the processing description to Groq, and only accepts “additional criteria” when Groq can find an exact quote in the description.
• Verdict + evidence: produces a final outcome—REQUIRED, CONSIDER, NOT_REQUIRED, or INCOMPLETE—with an evidence-backed report, then records one row in dpia_screenings and one finding row per met criterion in dpia_findings.
• Discord notifications: if the verdict is REQUIRED, it sends the report to Discord and shows a “required” completion page; otherwise it shows a completion page with the verdict and reasoning.
• Weekly digest: every Monday, summarizes recent dpia_screenings verdict counts for the lookback window and posts the digest to Discord.

Use cases

• GDPR DPIA triage for SaaS product changes submitted by internal teams
• Automation engineers needing repeatable GDPR decision support inside n8n
• Privacy operations teams tracking DPIA outcomes over time with table-backed evidence
